We have been running them out of a 30" hart tube at 3050 fps. Accuracy is really good in the 3's. I'll have more leater.

What twist are you running? I'm working up a 208 A-max load in my 26" RUM (1-10"). It is showing promise. I might as well see if the 230's will fly for me. I would be pretty close to my 208 for drop at 1k and both are within a few fps, but with 10% more energy

I know it's not a 300RUM but Kirby Allen has his 300AX that I think would get you 3000 fps with the 230's in a 26in. tube

Im building of a remington 700, since its what I have, and a lot of people really dont like the lapua based cartridges on them. I have talked to a smith and he said its the bolt face really and not the action thats the problem. He said that opening the boltface on a typical bolt becasue of the extractor.. or something like that and that when rem made their lapua they redesigned the bolt. I wonder if I got one of remingtons lapua bolts though...... a 300 lapua improved does sound sexy
